python - 为什么我得到 flask.cli.NoAppException : While importing "application" ImportError was raised?

Question

我在更正一个与 SQLAlchemy 相关的错误后收到此错误:

flask.cli.NoAppException: While importing "application", an ImportError was raised:

File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/flask/cli.py", line 235, in locate_app
    __import__(module_name)
  File "/Users/Ryan/Desktop/HCS/project/application.py", line 6, in <module>
    from passlib.apps import custom_app_context as pwd_context
ImportError: No module named 'passlib'

passlib 模块是在:/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/flask

环境变量设置在 FLASK_APP=application.py。这是在安装 flask 的文件夹中设置的。我试过手动将文件放在上面引用的文件夹中并使用 pip 无济于事。我该如何解决这个问题？

实际上，passlib是一个独立的图书馆。它不应该在 flask 中。尝试安装它:

pip install passlib
